In my opinion, yes and no. No one has truly achieved omnipotence in the force in terms of feats. Vitiate, sidious, and nihilius came close in legends. Such as Reality warping, matter and molecular manipulation etc. so theoretically yes, but it has never happened before. Now the force itself as a entity, yes it is. But to the best of my knowledge there has been no physical embodiment of the force.

No. The force is all and nothing and has unlimited power.
the bedlam spirits are omnipotent but don't have total power of the force because nothing can have total power of the force not even one-above-all without the force nothing can exist

That doesn't even make any sense. The Force isn't a thing in Marvel, and if it was, TOAA would be above it because that's literally what he is. Also, if the Bedlam Spirits don't have control over the Force, they aren't omnipotent.
